Risk Factors in ABO Blood Group for Coronary Artery Disease
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 5
Abstract
Introduction: There are many reports regarding the association between ABO and Rhesus blood groups and coronary artery disease. ABO blood groups, in particular non-O blood groups, have been suggested to be associated with several cardiovascular risk factors, and even higher risk of ischemic heart disease, cerebral ischemia of arterial origin, and of developing severe manifestations of atherosclerosis. Aim: The aim of this study was to study the prevalence of risk factors in ABO blood group of coronary artery disease and to study immediate prognosis and mortality. Materials and Methods: This study was conducted in the Department of Cardiology and Medicine, Government Rajaji Hospital, Madurai. Patients admitted with clinical features of acute myocardial infarction confirmed by electrocardiogram and patients admitted with angina pectoris clinically were included in the study. Detailed history, general examination, cardiovascular examination, and relevant investigations were done in all patients. Results: The incidence of coronary artery disease is predominant in “A” Group. The incidence of diabetes mellitus (DM) and hypertension (HT) is 40% and 30% in “A” Group which constitutes about 21.2% among the population. In female population, menopause is the main risk factor. Here, also the incidence of DM, HT, and hypercholesterolemia is most commonly found in “A” Group individuals. About 66% contribution is from the smoker. DM contributes to 22%. Conclusion: The type of ABO blood group seems to have an impact on the risk of coronary artery involvement and the type of blood group effects on the severity of CAD. Smoking affects the prognosis whichever blood group they belong. About 66% incidence of left ventricular clot is seen among smokers.
